DC Product Specifications
Sensing Beam
Adjustments All models except emitters: 15-turn slotted brass GAIN (sensitivity) adjustment potentiometer
(clutched at both ends of travel)
Supply Protection Circuitry Protected against reverse polarity and transient voltages
Output Configuration SPDT (complementary) solid-state dc switch; Choose NPN (current sinking) or PNP (current sourcing) models.
Light operate:
N.O. output conducts when the sensor sees its own (or the emitter's) modulated light
Dark operate: N.C. output conducts when the sensor sees dark
Output Rating 100 mA maximum (each output)
Off-state leakage current: <5 microamps at 30V dc;
On-state saturation voltage: <1V at 10 mA dc; <1.5V at 100 mA dc
Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs
Overload trip point
≥
150mA, typical, at 20ºC
Output Response Time Diffuse and retroreflective modes: 1 millisecond on and off
Opposed mode: 1 millisecond on, 0.5 millisecond off
Fiber optic mode: 0.25 millisecond on and off
Indicators Two LEDs: Green and Yellow
GREEN glowing steadily = power to sensor is "on" Opposed emitters: Green power "on"
GREEN flashing = output is overloaded
YELLOW glowing steadily = light is sensed; normally open output "on"
YELLOW flashing
= marginal excess gain (1-1.5x) in light condition
Repeatability Diffuse and retroreflective modes: 250 microseconds
Opposed Mode: 120 microseconds
Fiber optic mode: 60 microseconds
Construction Housings are die-cast zinc alloy with black epoxy powder paint finish; lenses are acrylic
Environmental Rating IP67; NEMA 6
Connections 2 m (6-1/2 ft) or 9 m (30-ft) attached cable, or 4-pin euro-style quick-disconnect fitting; Cables for QD
models are purchased separately
Operating Temperature -20º to +70ºC (-7º to 158ºF); Maximum relative humidity 90% at 50ºC (non-condensing)
Infrared, 880 nm for opposed and diffuse; Visible red, 660 nm for fiber optic and retroreflective modes
Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than:
Diffuse and retroreflective models: 20 milliamps
Opposed mode: 30 milliamps (emitter), 10 milliamps (receiver)
Fiber optic models: 30 milliamps
